Bi-amped, with a passive mid high crossover, a 12-enclosure array can be driven by either 3 x iK42 amplifiers (2-box resolution) or 6 x iK42 amplifiers (1-box resolution). With the number of amplifiers determined to suit the venue, the application and the budget, the commercial advantages of scalable resolution are clear:

• Design systems to suit budget targets
• Dynamic deployment within a venue or site where the main PA is driven with more amplifier channels than may be necessary for delays
• Adaptable rental pricing based on event dynamics and clients’ resources

  Display Optimisation

  • DISPLAY is an extremely powerful prediction and array configuration tool. Instead of using a standard geometric model, DISPLAY is based on an industry-leading acoustic model accurate to within ±1dB of measured data, and delivers unrivalled coverage consistency over the audience  right from switch-on.

    Amplification, DSP And Networking

    • WPL is designed as a complete system with dedicated, high-performance iKON multi-channel Class D amplifiers. For 1-box and 2-box resolution, the iK42 4-channel amplifier delivers very high power outputs and features high-speed Ethernet communication for system control and monitoring via Martin Audio’s VU-NET software, plus Dante™ digital audio networking. With the option to transmit digital audio over a single CAT5 cable, quality is maintained over long cable runs and integration with other devices in the sound system is straightforward.

      Dual Hybrid Horn LF Section

      • Hybrid technology combines the efficiency and impact of a bass horn with the low frequency extension of a bass-reflex enclosure. With a typical efficiency improvement of 4dB compared to direct radiator low-end designs of competitors, a WPL array has a noticeable advantage over direct radiator arrays when projecting maximum LF output over distance.

        Horn Loaded Midrange Section

        • The patented mid-range section is central to the signature sound and superb horizontal pattern control of WPL. Compared to direct radiator midrange designs of competitors, the horn design of WPL mid has the advantages of both greater output and superior horizontal pattern control which does not vary significantly with frequency.

          High Frequency Section

          • Operating from 4kHz upwards, the HF section of the WPL utilizes 3 x 1” (25mm) exit neodymium compression drivers mounted on individual horns with true 90° horizontal constant directivity characteristics.

            Rigging

            FAST AND EASY RIGGING – DEPLOYMENT SPEED

            • Safety, simplicity and speed are essential aspects of a rigging system which the WPL three-point rigging system fully addresses. The rigging design allows for suspension of up to 24 enclosures, with DISPLAY software calculating the splay angles from 0°-7.5° needed to produce the desired vertical coverage. DISPLAY also determines the safe limits and tilt angle of an array and confirms compliance with specific safety standards, including BGV-C1, prior to deployment.

              FRONT RIGGING POINTS

              The front hinge points at the top of each WPL enclosure over-extend to ensure that there is plenty of ‘finger-room’ for riggers to pin enclosures together. As well safeguarding hands, this over-extension also gives useful latitude when connecting the lowermost box in an array to the uppermost box on a dolly which may not be on level ground, such as a festival site. As the hang is lowered, a second pin locks the hinge in place in its unextended position to minimise the gap between enclosures at the hinge point to just a few millimetres, ensuring vertical coverage consistency.

               
              

              

               
              

               
              

              REAR RIGGING POINT

              The rear rigging point sets the inter-cabinet splay angles determined by DISPLAY, and the design allows the angles to be easily set by a quick-release pin while enclosures are in their closed-up transport positions on the dolly. Once the uppermost enclosure on the dolly is attached to the array and the array is lifted, the dolly enclosures open up to the correct splay angles. A second pin locks each in place.
